How to Cut Your Energy Bill by £200 This Year

The opportunity

Energy is one of the biggest household bills — and one of the most neglected. Many UK households are still on their supplier's default tariff, paying hundreds of pounds more than they need to. The good news: switching is straightforward and the savings are real.

Step 1: Know what you're paying now

Before you can compare, you need your current annual usage in kWh. You'll find this on your latest bill or in your online account. Note down both your gas and electricity usage separately.

Also note your current unit rates (pence per kWh) and standing charges (pence per day). These are your baseline.

Step 2: Compare on Uswitch

Go to Uswitch.com and enter your usage. It will show you every available tariff ranked by annual cost. Filter for fixed-rate tariffs if you want price certainty over the next 12–24 months.

Pay attention to the exit fees on any deal you're considering — some fixed tariffs charge £30–£50 per fuel to leave early.

Step 3: Consider a smart meter

Smart meters are free and give you real-time visibility of your energy use. Many suppliers offer better tariffs exclusively to smart meter customers. If you don't have one, call your supplier and request one — they're legally required to offer you one.

Step 4: Reduce usage without discomfort

Switching supplier is the biggest lever, but there are easy habit changes that add up:

• Turn your boiler flow temperature down to 55–60°C (can save £100+/year on a combi boiler)
• Wash clothes at 30°C instead of 40°C
• Use a slow cooker instead of the oven where possible
• Switch to LED bulbs if you haven't already — they use 75% less energy
• Draught-proof your front door — a £10 seal makes a noticeable difference

Step 5: Check government support

If you're on a low income, receiving certain benefits, or have a medical condition in your household, you may be entitled to the Warm Home Discount (£150 off your electricity bill), the Winter Fuel Payment, or the Priority Services Register. Check GOV.UK to see what you qualify for.

Expected savings

Switching supplier alone typically saves £100–£300/year depending on your usage and location. Add the boiler flow temperature change and you're often past £200 without any lifestyle sacrifice. If you qualify for the Warm Home Discount, that's another £150 on top.

This is the highest-ROI action most UK households can take this year.
